sPEoIFIcATIoN forming part of Letters Patent No. 485,962, dated Novembere,- 189e.l 1f l Application tied october 27,1890. serial 110.369,469.(Numan.) Patented in Germany-Apel 2s, las?. No. 41,599, attainAustria-Hungary July l, 1887, No. 26,502 and No. 61.312. l 'i T0 allwhom, it may concern,.-

Be it known that I, CARL AUGUST EMIL MEINICKE, a subject of the King ofPrussia, residing at Clausthal, in the Kingdom of Prussia, Germany, haveinvented new and useful Improvements in Ore-Separators, (for which' Ihave obtained Letters Patent in Germany, No. 41,599, dated April 28,1887, and in .cal longitudinal section of the apparatus. Fig. 2is aplan; and Fig.3 is a detail section on line 1 1 of Fig. 1 through one ofthe partitions, the channel d being shown i-n dotted lines m n o p.

A is a supply-chute discharging into a hopper a, and A' is theofttake-chute at the opposite end of the hopper and in alower plane thanthe chute A. Below the hopper a is a casing B, having avertically-extending zigzag channel c, at one side of which is formedaseries of chambers f f2 f3 f4, provided with water-inlet valves h h2 h3h4, and communieating at their inner ends with the said channel c bymeans of passages e e2 e3 c4. The opposite side of the casing B isprovided with a series of upwardly and outwardly inclined channels d',d2, d3, d4, and d5, communicating at their lower ends with the verticalchannel c, and at their upper ends the channels d d? d3 d4 lead intochambers K over plates k. The chambers K at one side of their lowerportions are provided with lateral outlet-pipes d dsc d20 cl, havingordinary rotary slidevalves d". The channel c may be closed or partiallyclosed at the lower ends of the channels d2 to d4 by means of slides s2s3 s, carried by rods S5, extending up through the said channels andprovided at their upper ends with adjusting-nuts s6. At the upper end ofupper edge of which thewastev`wateryiiow`s also be adjusted rod and nut.

'lheoperation is as follows: 'lhe ground ore or mud is fed from thechute Ainto the hopper @,and passes thence through the opening b intothe upper end of channel c, where it meets the ascending current otwater from one or all of the cham bers f to f4,which causes the lightworthless matter to rise with the water, passing up through the channeld5 to the oltake-chute A. The heaviest ore particles will descend to thebottom of the channel c and be carried up through the channel d. and outthrough pipe (ZO into any suitable receptacle, and so with the other oreparticles, which will pass through the other channels (Z2 to d4 in likemanner. If the force up or down by means of'a into the outlet-chute A',and this gate may of water through the chamber f is insuflil cient, thenone or more of the valves h2 to h4 may be opened, as will be readilyunderstood.

IE the materials being treated so require, one or more of the .chambers-f and corresponding channel d may be cut out by closing the channel cby means of the proper slide d2, dto., whereupon only the channels abovesuch slide will be operative.

Should it be found that any light ore partimay be raised a littlehigher, vent such action. will be collected in suitable receptaclesplaced under the outlet-pipes d d4".

Having thus described my invention, what I claim is- 1. An ore separatorand grader comprising the hopper, a casing thereunder provided with avertically-extending channel c,.communi cat-ing with the outlet in thebottom of said hopper, a series of valved water-supply chambers at oneside of the said channel communicating therewith, and a series ofseparate and independent channels leading upward and outward from thechannel c to separate outlets, substantially as set forth.

2. Thecombination, in an ore separator and grader, with the hopperhaving an opening in which will preits bottom, of the casing under thehopper, provided with a vertically-extending channel cles are passingover the gate d50, said gate The graded concentrates IOO e- Y l 485,962
